By observing the success of the Internet and packet-switched networks, recent initiatives such as NGN (next generation networks) and IMS (IP multimedia subsystems) have been undertaken to provide a seamless architecture for various access technologies.
Besides other innovative approaches, by integrating different technologies – SDP (service delivery platforms) and IMS, for example – easy service delivery, execution and management are now possible. Other issues such as point-to-point and broadcasting communications, data and multimedia oriented services, mobile and cellular systems, fast fiber and mobility remain challenging tasks and, to say the least, the end-to-end picture is still unclear.
On the other hand, there are efforts such as 6LoWPAN, which tries to connect resource-constrained sensor networks to the Internet to provide a ubiquitous environment, supporting the concept of the Internet of Things (IoT) in some way. This leads to a highly distributed network of devices communicating with human beings as well as with other devices. With the increase of heterogeneity, it becomes very difficult to ensure proper interactions among devices in a unified manner.
To summarise, we can say that even though the recent advances in network convergence offer new realities, there are several research challenges and issues that need to be addressed. For example, the heterogeneity of networks imposes difficulties and challenges in ensuring network security, QoS provisioning, route optimisation and so on. Applications relying on underlying mechanisms could perform well or satisfactorily when the underlying mechanisms can meet the expected standard levels of their operations.
Suitable topics include but are not limited to:
- Next generation networks
- IMS and related technologies
- Integration of IMS and SDP
- IPTV architectures and standards
- Security issues in future networks
- IPTV/IMS management.
- QoS and QoE provisioning
- 3P and 4P service provisioning
- Accounting and billing
- Regulatory issues
- Streaming services over wired/wireless access networks
- 6LoWPAN architectures and standards
- Mobility issues in 6LoWPAN
- Route optimisation
